McDowell Sonoran Preserve: Marcus Landslide Trail

Phoenix - Scottsdale - Mesa

The Marcus Landslide Trail leads to one of the largest landslides in the history of Arizona. An estimated 194 million cubic feet (25.8 billion pounds) of rock and debris slid off the side of East End Peak before settling about a mile from the initiation zone. Energy released by the slide is thought comparable to an atomic bomb in an event that may have only lasted a few minutes.
